Also you dont need to make full cycle of boromir/merry healing. You need to make the math how much times you need to pump merry and boromir, because equality is not the base.
I'd like to look into optimal math calculations as well, though I think what NK actually did worked great. Let's see... you have 4x
NFFatRoD and
A Light in His Mind and 4x
TSC for a total of 20 wounds healed. With their starting vitality, you get 28 exerts total. Merry starts at str. 3 (though 5 would be better if he has a
Hobbit sword...?)
Boro x4: Merry is 17
Merry x4 (twice x2): Companion is +34
These two should go together because the first
NFFatRoD loses initiative and heals 8. So now 20 exertions to go...
Boro x16: Merry is 65
Merry x4: Companion is +130 (+174 total)
Boro x12: Merry is 53
Merry x8: Companion is +212 (+246 total)
Boro x8: Merry is 41
Merry x12: Companion is +246 (+280 total)
Boro x4: Merry is 29
Merry x16: Companion is +232 (+266 total)
Looks like a mostly balanced approach is the way to go.
EDIT: Fixed math error.
